How EVs work in Pokémon
Effort Values (EVs) are stat training points you earn by defeating wild Pokémon — every species you KO drops 1, 2, or 3 EVs into a specific stat (look up Yield in the Pokédex). A Pokémon can hold up to 510 total EVs with a cap of 252 per stat. The standard competitive spread is 252 / 252 / 4 — max two stats, dump 6 leftover EVs anywhere useful (most often into a defensive stat).
The level-50 EV math
At level 50, every 8 EVs gives you +1 to a stat (because the stat formula multiplies the EV term by level/100, then floors). So a "252 in Speed" spread = +31 Speed at level 50, not +63. This matters for competitive play because nearly all official formats are level 50.
At level 100, every 4 EVs gives +1. That's why we use 252 (the highest multiple of 4 within the cap) and not 255 — the last 3 points would be wasted.
The standard spreads explained
252 / 252 / 4 (offensive)
For sweepers. 252 in your attacking stat, 252 in Speed, 4 in a defensive stat (Def or SpD). The 4 leftover EVs matter only against weak chip damage (Stealth Rock pebbles, weather, sandstorm) — every little bit helps.
252 / 252 / 4 (defensive)
For walls. 252 in HP and 252 in your defensive stat (Def or SpD), 4 in the other defensive stat. HP is almost always max-EV invested for walls because it multiplies both Defense and Special Defense effectively.
252 / 128 / 128 (mixed bulk)
For Pokémon that need to soak hits from both sides. Common on Pokémon like Heatran (good base 106 HP, decent 91 Def and 106 SpD), or Toxapex when running Black Sludge sets.
Custom speed creep spreads
Often the spread looks weird: 124 Spe Adamant on Iron Hands, for example. That's a speed creep — "just fast enough" to outspeed a specific threat (slow Glastrier under Trick Room? Outspeed Adamant Garchomp in non-Trick-Room? etc.) — and the rest of the EVs go to bulk. Use our stat calculator to find which spread hits your benchmark.
EV training shortcuts in Scarlet/Violet
Three things make Gen 9 EV training trivially fast:
- Vitamins (Protein, Iron, Carbos, etc.) — each adds 10 EVs to one stat, up to 252. Buy them at Chansey Supply, cost ~5000P each. Maxing one stat = 26 vitamins ≈ 130,000P. Painless if you've played past mid-game.
- Sandwich + Power item combo — make a sandwich with "Encounter Power: [Type]" to spawn waves of a specific type. Equip the matching Power item (Power Anklet for Spe, Power Belt for Def, Power Bracer for Atk, etc.) for +8 EVs per KO. You'll max a stat in 30–40 KOs (~15 minutes).
- Pokérus replacement: 'Held Item: Lucky Egg' for XP — not for EVs directly, but pairs with the above to double your training speed.
Resetting EVs without re-catching
Made a bad spread? EV-lowering berries: Pomeg (HP), Kelpsy (Atk), Qualot (Def), Hondew (SpA), Grepa (SpD), Tamato (Spe). Each lowers 10 EVs in the corresponding stat. Combine with friendship loss buffer (these berries also boost friendship if held). You can also reset 252 EVs in a single stat at the Vitamins shop NPC if you've reached the relevant story milestone.
